Fuel Pump Tappet Roller Assembly Cummins Engine ISC – Engine QSC

It transmits mechanical motion to the pumping section of the high-pressure pump, it operates within the fuel pump drive system. The roller follows the control profile and transfers force to the pump, enabling the pump to generate the pressure required for the fuel injection system.

The part is also listed for use in Cummins ISC 8.3 and QSC 8.3 / PACCAR PX-8 applications, while other catalogs also list it for use with ISL 8.9 / ISL 9,  QSL 8.9 / QSL 9 and the CCR1600 pump.

However, to ensure exact compatibility, you must verify the ESN (Engine Serial Number), CPL, pump model, and pump part number, because there may be different configurations within the ISC/ISL families.
